Douglas, whatever the origin of those translucent and fascinating 'Nautilus' pearls, the vortical structure remains mysterious (and contradictory to everything we are taught about pearl formation) except in terms of pure mathematics. The wonders of nature.
Heads up here, that among the possible explanations we seriously considered and discarded for those pearls was opercula, which the above comments may actually describe.
I agree Steve. And the operculum could have damage caused by predators, it mantle cells possibly initiating a "pearl" that carries this torzoidal shape...I mean, imagine all the things we could learn if we had animals at our disposal, a great pond and time
I purchased this golden cross.
4 missing pearls, diameter about 2,5mm, where should I get some replacement pearls?
If someone knows a source, natural or cultured, drilled on one side or undrilled, I would be happy to know!
